Garfield County uses three microcomputer systems, although one system should be adequate for most departments. Using an Apple IIc and two IBM Personal Computers, the agency processes jail records, handles fiscal control functions, and uses a modem for contact with other information networks and services. Past records on patrol operations, personnel, stolen items, and other subjects have also been computerized. When purchasing a microcomputer, users should first examine their needs and the types of software they will use. They should also buy a system that can be expanded. Software changes rapidly, but most software firms allow the user to upgrade software at a substantial reduction. Software should provide graphics and statistical capabilities and a data base program. All components of the agency should be involved in planning the system so that they will welcome rather than fear it. Games and sample tapes are useful as orientation devices. It is also helpful to contact outside agencies before writing a program, to see if they have information needs that the program can accommodate. Crucial questions to ask in planning for a system are the availability of support for both the hardware and the software, the cost and location of support and periodic maintenance, and the kind of software the system supports.
